Welcome to the M0001 Registry database project. If you own an original Macintosh through a Mac Plus, it is an original M0001 Macintosh model and you should register it here. There is no information required on this page, you may enter as much or as little as you are comfortable with. Apple has long since forgotten about your M0001, but here it lives on forever!

RE: SPAM - Spam bots occasionally find the site and input spam. The site is routinely monitored and will be cleaned of Spam. Please do not let the presence of Spam deter you. The site is active, and actively fighting spam incursions. Your data will be preserved. However, DO NOT BOOKMARK this page directly as it may change, rather bookmark the page that led you here or the original project homepage

There is no information required on this page, you may enter as much or as little as you are comfortable with. However, you will not be able to make changes once you post the entry to help combat vandalism and preserve the integrity of the database information. If you do make a mistake, please send your changes to the administrator to update your listing, however, you will need to identify yourself as the original poster of the entry. Likewise, should you sell your model M0001 Macintosh, please notify your buyer to register too, so that the new ownership may be reflected (i.e. location). If you make a mistake entering the serial number, please indicate in the description field for the correct serial number entry which incorrect serial number entry it is correcting. You may do this for any duplicate entries correcting or adding information to your original entry as well.

Ultimately, this searchable database will hopefully become a valuable research tool for vintage Macintosh hobbyists and academia, if not just an interesting picture of the usefulness of the original Macintosh model.

Your Model is determined by the serial number for the purposes of this database, regardless of what your M0001 has been converted into.

Note you can enter serial numbers for the Macintosh & Macintosh 128K (M0001), Macintosh 512K (M0001W), Macintosh 512Ke (M0001E), Macintosh Plus (M0001A), any variations not included here (P, D, etc.) and certain Apple disk drives designed specifically for use with the M0001 which manufacture information can also be derived from the above linked decoder. These include the Hard Disk 20 (M0135), 400K External Drive (M0130) and 800K External Drive (M0131) the serial number of which for the decoder is created by adding the model number to then end. So please register everything you have.

For RAM, you should only list that RAM that is permanently installed (soldered) in your M0001, not clipped on upgrades that can be removed. In the case of the Mac Plus, obviously all of the RAM is removable, but for this purpose consider 1-4MB "permanent", regardless if more has been added through 3rd party add-on boards.

Under description, feel free to list anything about your M0001 that is not taken care of in the database fields like that Dove MacSnap RAM & 512K SCSI upgrades, internal hard drives, accelerators, etc., as well as the color of paint you used, the type of modifications you've made and how you use it. Don't forget to click the "3rd party upgrade" box ONLY if you have added anything upgrading it beyond Apple's OFFICIAL upgrade path, i.e. 128K-512K-512Ke-Plus 1MB-2MB-2.5MB-4MB.
